Abstract

With the development of social economy, technological innovation is changing with each passing day, and performance requirements of oil-free bearings are getting higher and higher. The present invention provides a copper alloy material with high strength, wear resistance and corrosion resistance and a manufacturing method thereof. The chemical composition of the copper alloy material of the present invention includes: 57.0-62.0% of Cu, less than 3.0% of Fe, 1.0-3.0% of Al, 1.0-3.5% of Mn, less than 5.0% of Ni, less than 3.0% of Sn, less than 2.0% of Pb, less than 0.15% of B and less than 0.50%of Ti, with the balance being Zn. The manufacturing method includes compounding, melting, gas removing refining, modification, horizontal continuous casting, performance testing and machining. A production process is simple and components are easily controlled. Production through horizontal continuous casting or centrifugal casting is performed so that large-scale production can be achieved easily and social and economic benefit is good.

Description

technical field [0001] The invention relates to the technical field of copper alloys, in particular to a complex copper alloy material and a manufacturing method thereof. Background technique [0002] With the development of society and economy, technological innovation is changing with each passing day, and the performance requirements of oil-free bearings are getting higher and higher. In order to meet the needs of more complex and harsh application environments and places, such as offshore oil drilling, naval (engineering) equipment and other oil-free bearings, Oil-free bearings should have excellent comprehensive performance, especially corrosion resistance. How to enhance the corrosion resistance of oil-free bearings while ensuring that the physical properties of oil-free bearings are not reduced can not only increase the number of offshore oil drilling, but also the navy [industry] The safety and reliability of equipment, but also the ability to test the product's adap...
